CAR-ROOF FRAMEWORK.

Specification of Letters Patent.

Patented Apr. 19, 1910.

- for car roofs.

Another object of my invention is to provide a car roof framen-ork that shall be especially adapted to resist diagonal strains.

Another object is to provide a carline that sha-ll brace the roof against diagonal strains and shall also support the weight of the roof advantageonsl Still further objects of my invention are to provide a car roof framework that shall be simple to construct, inexpensive, durable and efhcient.

All these objects and others of detail in connection therewith will be made more readily apparent in the following specification and claims when taken in connection with the accompanying draw iugs.

With those objects in view, my invention consists of the combination of elements stated in the appended claims, but for the purposes of explanation, I have illustrated the preferred embodiment of my invention in the accompanying drawings, together with some modifications of details.

Referring to these drawings,Figure 1 is a top lan view of my roof framework showing tie roof partly broken away. Fig. 2 is a corresponding side elevation. Fig. 3 is atransverse section of the roof. Fig. 4 is a section on the line of Fig. 3, this section being on an enlarged scale. Fig. is a section on the line 5-4) in Fig. 1, this section being on an enlarged scale. Figs. 5. 6 and 7 are perspective views of slightly dilferent forms of carlines that may be used in my improved roof framework.

The usual plates at the top of the side walls 36 are indicated by-the reference numeral 15.

Each carline consists of an I-bcam 16 or other structural shape as shown in Figs. 5, 6 and 7. I will describe my invention for the I-beam, but it will be readil apparent that various other forms of car ines would fallwithin the scope of the invention as defined in the appended claims.

The web of the I-bcam 16 is split in toward the center part away from the ends and then the ends are screed sport at an angle to one another and to the main part of the beam or carline. The extremities 17' of the forked ends 17 are bent still farther apart until they lie in the same plane. Channels 18 are rabbeted in the plates to receive the half webs 19 of the extremities 17' of the carlines. Holes are made through the flanges on each side of the half web 19 and a yoke bolt 20 passes through these holes, thus binding the extremities of the carline to the plate 15 and the fascia 22. The nuts 21 clamp over the plate 20 which lies against the fascia. 22.

Within the channel of the Lbeam carline 16 are laid the blocks 23 and on top of these are the purlins 24 fastened to the cal-lines by means of the bolts 25. At the center of each carline is another block 26 lying in the channel of the I-beam and on this rests the ridge beam 27, the parts being fastened together by means of the bolts .28. The supel carlinos 29 are placed on top of the purlins 24 and the dates 15, and their upper ends are dove-tailed into the ridge beam :27. The lateral edges of the supcr-carlines 29 are grooved as shown in Fig. 4 to receive the lateral edges of the corrugated roof sheets 30. Other grooves are formed in the ridge beam 27 to receive the upper or inner edges of the roof sheets 30. Above the roof sheets 30 restin on the super-carlines 29 are the super-par ins 31, the supplementary ridge members 32 and the supplementary plates 32'. The ridge beam is-overhung by a sheet metal plate 33. On top of the sub-purlins 31 and the supplementary members 3'3 and 32' are the roof boards 34. Abovethese alongthc ridge is the running board 35. Atthe corners the car framework is braced with diagonal braces 37.

As will be seen on referring to Figs. 6 and '7, the carlines may have a. channel or U- section with the web either up or down.

Various other modifications falling within the scope of the appended claims are comprehended within my invention.

The diagonal portions 17 at the ends of the carlincs serve to brace the roof against diagonal strains. At the same time these diagonal parts 17 perform the usual load sustaining functions of the whole carline. In practu-m I have found that this carlinc is unusually strong and rigid in proportion to the amount of material employed therein and a roof framework comprising such canlines has great durability.

It will be readily understood that my roof framework is adapted for all kinds of roofs, althou h I have illustrated it in combination wit 1 a metal roof inside of the board roof.

I claim:

1. A car-line consisting of a flanged beam having the web split in from the ends, and the and parts spread at an angle to each other.

2. A earline consisting of a flanged beam having the web spilt in from the ends and the end parts spread diagonally apart, and the extremities of the end parts spread still farther so as to lie in the same plane.

3. In a car framework, plates, carlines, each carline consisting of a flanged beam, the web thereof being split in from the ends and the end parts spread apart and bolted to the plates, purlins and a ridge beam supported by the carlines, and a roof resting on said purlins.

4. In a car framework, plates, carlines,

each carline consisting of a flanged beam, the web thereof being split in from the ends and the end parts s read apart and bolted to the plates, filler looks lying above the Web of the carline between the flanges thereof, urlms and a ridge beam resting on said bloc s, and a roof supported by said purhns and ridge beam. 5. A carllne consisting of an I-beam havmg} its web split in from the ends and the on arts spread at an angle to each other. (S, n a car framework, carlines, each eonsistmg of a flanged beam having forked ends spree apart, fi ler blocks lying between the flanges of the earlines, purlins resting on said blocks, and a roof supported by said purlins.

In testimony whereof, I have subscribed my name.
